the best invention i've ever made that works perfect is a bottle from http://www.hpnotiq.com ((30$, and i can keep using it))

strong 750ml bottle in a vase of water, a small socket from a socket wrench set(cleaned of course) in the cork(cut to about 1/4 the length) and hollowed through to pack the weed. classic gravity bong with a classy touch. Its the baseline for all of our weed testing.

1 = never happened, im sure when it does i'll be very glad
2 = plant im growing now..3 is -not- possible. i've seen people throw up when they tried.
3 = good good strong stoned, alteration of the world..etc good weed.
4 = okay stuff, schwag pretty much.
5+ = dont even bother.

Numbers = hits from it. it burns like fire, will put any hair you dont have on your chest and if you already do, you'll be yeti-fied.
